During The Great War (aka: WW1) they were known as Trench Guns. The Germans tried to get them outlawed as "inhumane," but considering it was Germany that began using chemical weapons, nobody paid them much attention.

Due to having a surplus of m1917 availability, The WW1/WW2 M97 (winchest 1897) and the later WW2 M12 (winchester 1912) and the Winchester 1200 Combat shotguns were all fitted with the bayonette lug for usage with the m1917 16" bayonet, and IIRC some shotguns using this configuration were in still use up thru the Vietnam war
